EDWVARD D. PEPPERS, OF MOBILE, ALABAMA.

CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 706,449, dated August5, 1902.

Application filed January 25, 1902. Serial No. 91,266. (No model.)

To all whom, it may concern:

Be it known that I, EDWARD D. PEPPERS, a citizen of the United States,residing at Mobile, in the county of Mobile and State of Alabama, haveinvented certain new and useful Improvements in Car-Doors; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention,such as will enable others skilled in the art to whichit appertains to make and use the same.

My inventionrelates to improvements in car-doors, and more especially tothat class of car-doors to be employed upon railway fruitcars.

My invention possesses certain features of novelty that will hereinaftermore fully appear, reference being had to the accompanying drawings,wherein Figure 1 represents an outside view of a car upon which myinvention has beenapplied. Fig. 2 is a slightly-enlarged view of thedoors from the inside, showing the locking mechanism. Fig. 3 representsa section on the line 3 3, Fig. 1, looking in the direction. of thearrow. Fig.4 is a sectional view,enlarged, of the locking mechanism ofone of the doors; and Fig. 5 is a perspective View of the lookingmechanism removed from the car.

a I) represent a pair of outside doorssupported upon hinges c, saiddoors havinglbeveled edges adapted to firmly close the dooropening ofthe car. These doors are hinged upon and swing upon the outside of thecar.

In the framework d upon the inside of the car are slidingly mounted theupper and lower doors 6 and f, respectively. The up per door e isprovided with the vertically-disposed bars 9, allowing a freecirculation of air. The lower door f is also provided withvertically-disposed bars 9 and also with a screen it, covering thesebars. These two upper and lower doors .6 and f are free to slideindependently of each other and are each provided with a catch 'M,respectively. In the jamb of the door is located a vertically-disposedsliding barj, provided with upper and lower openings 70, through whichpass the catches 11 i, respectively, of the upper and lower doorseand f.Upon the lower end of this sliding bar j is provided a pin Z,

provided with a downwardly-projecting stop Z. This slidingbarj ismounted in the metal frame or casing m, which iucloses the same upon twosides, a stop m being provided upon the bottom of this frame or casing,upon which rests the lower end of the barj. Upper and lower openings n0, respectively, are provided in this frame m, through which pass thelatches i 1;, respectively, upon the upper and lower doors cf,respectively. This frame m and bar j are entirely inclosed in thedoorframe and are entirely concealed and protected from View either uponthe inside or the outside of the car.

19 is a rock-shaft passing through from the inside to the outside of thecar, said shaft carrying upon its outer end the folding hasp q, adaptedto be locked or sealed upon either of the eyebolts r 1" upon the outsideof the car.

The inner end of the rock-shaft 19 carries a crank 8, provided with anarm 25, adapted to engage the pinZ of the sliding barj.

The operation of the doors is as follows: In the position shown in Fig.1both doors e'and f are locked, the hasp q being upon the upper eyebolt rand the seal. passed there'through. The outer doors a 12 maybe left openor closed, dependent upon the cargoor the atmospheric conditions. Tounlock thedoors, the seal is broken and the hasp qis removed from theupper eyebolt/r and placed upon the lower one 1'. The parts will thenassume the positions shown in Fig. 2, the-arm t raising the pin Z, andconsequently the sliding bar j. which releases the spear-headedlatches't' t upon'the upper and'lower doors, respectively. Both doorsmay now be opened, or, if desired, only one door may be opened, theremaining door being left closed and again locked.

The doors will be automatically locked when closed'while y the slidingbar j is in its lower position, either singly or both simultaneously, itbeing impossible to again open either door until the hasp q is removedfrom the eyebolt r and swung into the position indicated by dotted linesin Fig. 1.

It will thus be seen that a Ventilating cardoor is provided, and whilefree circulation of air is provided through this door, yet perfectsecurityis attained, it being absolutelyimpossible to open either doorwithout breaking ICO the lock or breaking the sealcircumstances whichwould at once indicate that the contents of the car had been tamperedwith.

While I have shown my invention as embodied in the particular form shownand described, it will be understood that I do not limit myself. to theprecise details of construction, as many changes and modifications mightsuggest themselves to any one skilled in the art.

Having thus described my invention, What I claim, and desire to secureby Letters Patent of the United States, is

1-. In a car-door, the combination with a pair of upper and lowersliding doors, and latches carried by each of said doors; of a barmounted to slide vertically in the doorframe, a stop upon the lower endof said bar, means carried by said bar for engaging said latches, arook-shaft passing through the side of the car, a crank upon the innerend of said shaft provided with means for engaging said .stop upon saidbar, a hasp upon the outer end of said shaft to operate the same, andeye- 1 bolts upon the outside adapted to secure said hasp in its lockedand unlocked positions.

2. In a car-door, the combination with a pair of upper and lower slidingdoors, and latches carried by each of said doors; of a bar mounted toslide vertically in the doorframe, a stop upon the lower end of saidbar,
